4-1. Before driving
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes peri odically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding
down operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. ( P. 5 76 )
■For efficient use
●Shift the shift lever to D when driving.
In the N position, the gasoline engine oper ates but electricity cannot be generated.
The hybrid battery (traction battery) will discharge, requiring unnecessary engine
power to recharge.
●Drive your vehicle smoothly.
Avoid abrupt acceleration and decelerati on. Gradual acceleration and decelera-
tion will make more effective use of the electric motor (traction motor) without hav-
ing to use gasoline engine power.
●Avoid repeated acceleration.
Repeated acceleration consumes hybrid ba ttery (traction battery) power, resulting
in poor acceleration. Battery power can be restored by driving with the accelerator
pedal slightly released.
●Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may dis-
charge the hybrid battery (traction batter y). The vehicle cannot run if the hybrid
battery (traction battery) is discharged.

Driving
■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline engine
will start automatically in order to warm up. In this case, you will become unable to
switch to EV drive mode.
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the
following situations. When EV drive mode is canceled, a buzzer will sound and the
EV drive mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” display is low.
(  P. 112)
●Vehicle speed becomes more than about 25 mph (40 km/h).
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distan ce ranges from a few hundred meters to
approximately 0.6 mile (1 km). Driving is possible at speeds of less than approxi-
mately 25 mph (40 km/h). However, depend ing on vehicle conditions, there are sit-
uations when EV drive mode cannot be used.
(The distance that is possible depends on the hybrid battery [traction battery] level
and driving conditions.)
■Fuel economy
Your Lexus is designed to achieve the best possible fuel economy during normal
driving (using the gasoline en gine and electric motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy. To prevent gasoline engine warm up in order
to reduce noises, start the hybrid system with-
out starting the gasoline engine, pressing the
power switch with fully depressing the brake
pedal and pressing the EV drive mode switch.

Driving
Hybrid transmission
While the power switch is in ON mode, move the shift lever with the
brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: To improve fuel efficiency and reduce noises, set the shift lever in D for normal driving.
*2: By selecting shift ranges using S mode, you can control accelerating forces and
engine braking forces.
